The companies that own nuclear power plants in Sweden are responsible for adopting such measures as are needed in order to manage and dispose of spent nuclear fuel and radioactive waste from Swedish nuclear power plants and to dismantle the plants. According to the law, the Financing Act, the reactor owners shall pay a fee on nuclear energy production in order to fulfil this responsibility. The...

"If all the country's electricity were generated by nuclear power plants, the health risk would be equivalent to the risk faced by a regular smoker who smokes one extra cigarette every 10 years; or by an overweight person who increases his weight by 0.03 ounces; by crossing a street one extra time every 20 weeks; by increasing the national speed limit from 55 mph to 55.02; or by using a sub-com...

In this paper, an improved system to efficiently utilize the low-temperature waste heat from the flue gas of coal-fired power plants is proposed based on heat cascade theory. The essence of the proposed system is that the waste heat of exhausted flue gas is not only used to preheat air for assisting coal combustion as usual but also to heat up feedwater and for low-pressure steam extraction. Ai...

Here we show that combustion sources, including waste incinerators, metallurgical processes, power-heating systems and so on, are also important emitters of polybrominated diphenyl ethers (PBDEs) to the atmosphere. Geometric mean PBDE concentrations in the stack flue gases of the combustion sources ranged from 8.07 to 469 ng/Nm3. The sinter plants (24.7 mg/h), electric arc furnaces (EAFs) (11.3...

In this bachelor thesis, which is a part of the project RadioRoSo, we examine and analyze waste from Magnox power plants. These power plants were mostly situated in the Great Britain and they were operated between 1956 and 2015. The analyzed waste mainly consists of pieces of Magnox alloy AL80. Springs from alloy Nimonic 80A are also present in the waste and they are considered to be highly rad...

Uloženie nukleárneho odpadu vysokého stupňa v Nemecku Nuclear energy is very often used to generate electricity. But first the energy must be released from atoms what can be done in two ways: nuclear fusion and nuclear fission. Nuclear power plants use nuclear fission to produce electrical energy. The electrical energy generated in nuclear power plants does not produce polluting combustion gase...

A project on co-firing in large-scale power plants burning coal is currently funded by the European Commission. It is called COPOWER. The project involves 10 organisations from 6 countries. The project involves combustion studies over the full spectrum of equipment size, ranging from small laboratory-scale reactors and pilot plants, to investigate fundamentals and operating parameters, to provi...

The Bush Administration has made the expansion of nuclear power generation a centerpiece of its domestic energy policy. However, the White House has not addressed the practical issue of how to overcome the nearly three-decade-long aversion among U.S. electric utilities to investing in new nuclear plants. In today's deregulating market, utilities will not build new nuclear power plants unless th...

No public policy issue has been as difficult as high-level nuclear waste. Debates continue regarding Yucca Mountain as a disposal site, and-more generally-the appropriateness of geologic disposal and the need to act quickly. Previous research has focused on possible social, political, and economic consequences of a facility in Nevada. Impacts have been predicted to be potentially large and to e...
